Učionica je velika.

Učionica is a noun meaning classroom. It is feminine in Serbian.

You can often recognize many feminine nouns because they end in -a, and učionica follows that pattern. That matters because adjectives must agree with the noun in gender, number, and case.

So in this sentence:

• učionica = feminine singular noun
• velika = feminine singular adjective to match it

Because Serbian adjectives must agree with the noun they describe.

Since učionica is feminine singular, the adjective must also be feminine singular:

• masculine: velik
• feminine: velika
• neuter: veliko

So:

• Učionica je velika. = The classroom is big.
• Sto je velik. = The table is big. (masculine)
• Selo je veliko. = The village is big. (neuter)

Je is the 3rd person singular form of the verb biti (to be), so here it means is.

So the sentence breaks down like this:

• učionica = classroom
• je = is
• velika = big

Together: The classroom is big.

This is the normal Serbian equivalent of is in a present-tense sentence like this.

In standard Serbian, je is normally kept in a sentence like this:

• Učionica je velika.

Leaving it out would usually sound unnatural in ordinary standard usage.

Serbian sometimes omits forms of to be in certain styles, headlines, or informal speech, but for a learner, the safe and correct form here is definitely:

• Učionica je velika.

Serbian does not have articles like English a/an/the.

So učionica can mean:

• a classroom
• the classroom

The exact meaning depends on context.

In this sentence, English often translates it as The classroom is big or A classroom is big, depending on the situation. Since you said the meaning is already known, the important grammar point is that Serbian simply does not use a separate word for the.

The most neutral word order here is:

• Učionica je velika.

But Serbian word order is more flexible than English, because the endings help show grammatical roles.

You may also see:

• Velika je učionica.
• Je li učionica velika? (Is the classroom big?)

Changing the order often changes the focus or style, not the basic meaning.

For a beginner, Učionica je velika. is the best standard pattern to learn.

A rough pronunciation guide is:

oo-chee-oh-nee-tsa

More carefully:

• u = like oo in boot
• č = like ch in church
• i = like ee in see
• o = like o in a short, clear off-type sound, but without becoming a diphthong
• n = normal n
• i = ee
• c = like ts in cats
• a = like a in father

So:

• učionica ≈ oo-chee-OH-nee-tsa

The stress is commonly on o: učiOnica.

A rough pronunciation is:

VEH-lee-kah

Sound by sound:

• v = English v
• e = like e in bed, but cleaner and shorter
• l = clear l
• i = ee
• k = k
• a = a in father

So:

• velika ≈ VEH-lee-kah

Yes. Both the noun and the adjective are in the nominative singular here.

That is because učionica is the subject of the sentence, and the predicate adjective velika matches it.

So you have:

• učionica → nominative singular feminine
• velika → nominative singular feminine

This is the basic dictionary form of both words.

Yes, both the noun and the verb/adjective would change to the plural:

• Učionice su velike.

Breakdown:

• učionice = classrooms
• su = are
• velike = big (feminine plural)

So singular:

• Učionica je velika.

Plural:

• Učionice su velike.

Yes, but it changes the structure slightly depending on what you mean.

If you want to say the big classroom, you can use the adjective directly before the noun:

• velika učionica = big classroom

But in your full sentence, the adjective is a predicate adjective, so it comes after je:

• Učionica je velika. = The classroom is big.

So compare:

• velika učionica = a big classroom
• učionica je velika = the classroom is big

It is the most common and standard word for classroom.

It comes from učion- related to learning/teaching, plus a noun ending. In everyday Serbian, učionica is the normal word you should learn first.

In some contexts, people may use other words depending on the type of room or institution, but učionica is the standard general word for a classroom.

You make it negative by changing je to nije:

• Učionica nije velika. = The classroom is not big.

So:

• je = is
• nije = is not

This is a very useful pattern:

• On je visok. = He is tall.
• On nije visok. = He is not tall.

A common way is:

• Da li je učionica velika?
• Je li učionica velika?

Both mean:

• Is the classroom big?

For learners, both are useful, but Da li je... is often especially easy to understand and build.

So from the statement:

• Učionica je velika.

you can make a question:

• Da li je učionica velika?

You can add veoma or vrlo before the adjective:

• Učionica je veoma velika.
• Učionica je vrlo velika.

Both mean:

• The classroom is very big.

So the structure stays the same:

• noun + je
  • adverb + adjective

Example:

• Učionica je veoma velika.
